Steve Trevor was a Major in the US Army, and had a long term romance with Wonder Woman, initially without realizing that she was actually his colleague Diana Prince. He was killed by Doctor Cyber, causing Wonder Woman to relinquish her powers.
Col. Trevor then returned to the previous Steve's position at the Pentagon. After he learned Diana's secret identity at the start of the Crisis on Infinite Earths, Steve and Diana married with the blessing of Diana's mother Queen Hippolyta shortly before both of them were erased from existence by the Crisis on Infinite Earths.
As The Patriot/Wonder Man: By a scheme of Angle Man, who stole the super powers of Wonder Woman, Steve was led to take them in the form of pills that gave him these superpowers, believing that Diana would marry him.

- This version of Steven Trevor (Earth-One), including all history and corresponding appearances, was initially erased from existence following the collapse of the original Multiverse in the 1985–86 Crisis on Infinite Earths limited series. However the ending of Convergence retroactively prevented that collapse, saving all the alternate realities, though in an "evolved" form. Even though versions of the character may have since appeared, this information does not apply to those versions.
